So, Service light has come up on the car and i've done about 4k in it since purchase. So time for a fresh set of plugs and oil. As i'm fairly new to RS Meganes. I was wondering no your advice regards to plugs. I've come from JDM cars (subaru) and in my impreza i would always run NGK Iridium with a heat range of 6 as it was running 400+. I now own a wonderful R26. It is fitted with a mapped RS275 engine and runs 630 cc injectors and a stock turbo running 325hp and 340 ft/lbs. What plug am i best getting for this level of power/fuelling. Feels like NGK would be best and probably a heat range of 7? Is it worth re-gapping any plug i get? And if so to what gap? Does anyone run anything different or have a recommended set up for my state of tune.
Thanks, spot on. Would they need re-gapping or just as they come is ok ? Usually re-gap gives them a better spark for the extra fuel. Is it the same for the Meg's?
